    • A converter of 6-bit input includes a reference voltage generating circuit generating 17 reference voltages, a first switch circuit having 19 switch pairs each including MOS transistors for selecting two adjacent reference voltages in accordance with the four most significant bits, a second switch circuit including a series circuit of MOS transistors for dividing the selected two reference voltages into four to obtain three intermediate voltages, and a third switch circuit for selectively outputting the lower of the selected two reference voltages or one of the three intermediate voltages. In a second mode in which a gray level having a smaller ON-resistance of a MOS transistor than that in the first mode is selected, the number of MOS transistors used in the first and second switch circuits for voltage division is increased.
